Climate change threatens us all

■ LAST week, 11,000 scientists issued a bleak warning that the climate crisis will bring “untold suffering”. We need to take action to help reduce global greenhouse gases and encourage bigger polluters, such as America and China, to follow suit otherwise we will face unmitigated disaster.

In this eventuality, we need to have a worse-case scenario survival plan to provide the basics of food, water, shelter and warmth.

This is not alarmist. What is alarming is that many politicians think the UK general election is about Brexit – climate breakdown would put an end to all that. Geoff Naylor, Winchester, Hants

■ I’m surprised that none of our towns or cities have ever tried, or even piloted, providing free public transport and banning all nonessential vehicles from town centres to combat climate change. The environment, the high street and city centres would all benefit from being pollution-free.

It would also help lazy motorists like myself who would rather drive and take a chance on finding a parking spot than walk 30 yards to the bus stop for a stress-free 10-minute bus ride.

■ I wake up at night worrying about what state our planet is going to be in 100 years from now. It’s about time that all countries came together and agreed a plan looking forward into the next century. This is something we should do for our children and grandchildren to create a sustainable future that will help to reverse the climate-change problems we already have. Jonathan Taylor

Barry, Vale of Glam

■ The good ship Earth has been slowly sailing towards the port of disaster for decades and, as with any vessel of magnitude, it will take some time and distance before its relentless course can be altered.

The captain and crew need to realise the predicament we are in and have the good sense to change direction before it’s too late. Brian Davies

■ Climate change will be the greatest self-inflicted catastrophe humankind will ever face.

It will dwarf any war, plague, famine or drought. All previous human suffering, through its global all-consuming cataclysmic impact, will pale into insignificance against it. Who do you trust to tackle the climate emergency, Bullingdon boy Boris or Jeremy Corbyn, who has spent his career campaigning against injustice? Norman Roderick Jones Barton St David, Somerset

■ I read about the possible downgrading of environmental regulations that can, among other horrors, enable more fracking.

Then there’s the acceptance of poor animal welfare standards that certain trade deals will entail.

I look at what Trump has done in bulldozing protection for the environment and I worry it could happen here.

The climate emergency is more important than Brexit, and we British environmentalists have a duty to take responsibility for our own country.

E Linton, Reading, Berks

■ To tackle climate change, we need to curtail the greed of those at the top and encourage economy through education.

I also suggest we cut back on chemical cleaning products.
